VELOCIPEDE.

Application led January 5, 1927. Serial No. 159,168.

will be highly efficient in use and economical in manufacture.

Among lthe severa-l objects of the invention is to provide a velocipedehaving a novel assembly of parts for propelling the same.

A still further object of the invention is to 'provide a velocipedewhich is` propelled by the weight of a body thereon.

Other objects will appear hereinafter.

The invention consists in the novel Combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings, showing the preferred form of construction and in which: 'Y

Fig. 1 is a typical side elevational view of the invention;

Fig. 2 is a longitudinal sectional detail view of the invention; and

Fig. 3 a sectional detail view of the invention taken substantially online 3-3 of Fig. 1.

In the drawing, lindicates a body platform supported for traction bywheels 11 and 12. The wheel 12 is Carried by an axle 13 secured to abolster 14 supporting the rear end portion of the body 10. The wheel 11is Carried by an axle 15 supported by a steeringr fork 16. This fork 16is formed substantially U-shaped and has connection with a steeringrpost 17 as at 18. This post 17 projects upwardly through an opening 19formed in the platform 10 at its forward end portion. The post 17 isjournaled in a sleeve 2O secured in any suitable manner to the platform10 at its forward end portion. The post 17 is supported in journaledposition within the .sleeve 2() through the medium of a collar 21secured to the post 17 by a set screw 22. The upper end portion of thepost has secured thereto a` handle bar 23 which facilitates the operatorto turn the wheel 11 to guide the platform during traction.

Formed in the platform 10 intermediate its end portions is an elongatedslot 24 and working in this slot 24 is a propelling bar The lower endport-ion 26 of the propelling bar- 25 has secured thereto inv anysuitable manner, a rubber knob 27 for reasons hereinafter set forth. Theupper end portion 28 of the bar 25 1s hingedly connected to a seat 29through 'the medium of a hinge structure 30. This hinge structure 3d isof the spring tyie andthe spring 31 `thereof normally functions toreturn the bar 25 to the position illustrated in Fig. 1. The seat 29 hasits forward ond portion 31 Connected to the platform 10 through themedium of a resilientstrip 32. This strip 32 is bent substantiallyU-shaped and has its end portion connected to the forward oud portion ofthe seat as at 34. The op- ].iosite-limb portion 35 of the strip S2issecured to the forward end portion of the platform as at 36. The strip32, due to its resilient properties, functions to elevate the seat 29from the position illustrated in Fig. 2 to the position illustrated inFig. 1. Downward movement of the seat 29, in a manner hereinafter setforth, is limited by a stop block 37 secured to the rearward portion ofthe platform lO.

ln use the Child positions himself on the seat 29 with his feet restingupon the platform 10. The child supports himself so as to permit thestrip 32 to place the seat 29 in the position illustrated in Fig. 1. Inthis position of the seat 29, the bar 25 will be urged into the positionillustrated in Fig. 1 through the medium of the springl 31. The Child inthis position places his hands on the handle bar 23 to guide thevelocipede when tractioned. To propel the velocipede the Child lets hisfull weight rest upon the seat 29 and this weight will force the seat 29downwardly and during this downward movement the rubber knob 27 willbear against the surface over which the velocipede is to be tractioned.Due to the inclined relation between the bar 25 and the seat 29 thedownward movement of the seat by 'the weight of the body7 will bear uponthe propeller bar 25 and inasmuch as the rubber knob prevents thepropeller bar 25 from movement independently of the veloeipede, thisdownward movement of the seat 29 will act upon the bar 25 to propel thevelocipede in a forward direction. This operation is repeated by theChild raising his body from the seat to permit the seat and propellerbar to return to their positions, illustrated in Fig. 1. Continuation ofthis operation will propel the velocipede about.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into efi'ect, this is capable ofvariation and modification, without departing from the .spirit of' theinvention. I, therefore, do not` wish to be limited to tbe precisedetails of construction set forth, but desire to :ivnil myself of suchvariations'nnd motlilientions us come within the scope of tbe appendedClaims.

Having thus described my invention what I elaiim as new and desire toprotect by Letters Patent. is:

1. In :t veloeipecle, a wheel bearing platform, n sent member, aresilientl strap operatively connecting tbe seat member to the platformand normally supporting the seat member from saidy platform andfunctioning to permt movementof tbe seat member relatively to saidplatform, a propeller member, und a springr hinge` operativelyconnecting,r the propeller member to tbe seat member, sniil propellermember being operabley by movement of tbe seatV member relative to theplatform for propelling said platform.

Q. In n velocipede, :i wheel bearing plat- `form, nfeeat member, aresilient strap op erntively connecting the sent member to said platformund normally supporting tbe seat member 'from tbe platform andfunctioning to permit n'iovrment of tbe seat member relutively to seidplatform, n propeller member, :1 rubber knob carried by tbe surfaceengaging-im end ol' tbe propeller member, nml :L spring' bingeoperatively connecting tbe propeller nieinberto the seat member, saidpropeller member being operable by movement ol tlie sent member relativeto the l'iluti'orm for propelling .suicl platform.

ln iiy velocipede, u wheel bearing plutform having an elongated slotformed therein, n. sont member, u substantially U shaped resilient stripoperatively connecting the sent member to the platform and normallysupporting the sent member for movement relative to tbe Suid platform,:1 prolieller bnr operable in the slot and nornmlly extendingsubstantially nt nn inclination willi reepect to tbe platform, und :ispring binge operutvely connecting' tbe upper end portion ot tbeprolieller bnr to tbe sent member.

In testimony whereof I :lllixi'ny signntnre.
